Battery Status
When battery voltage drops below acceptable level, the displayed value will blink.
If used as remote display for DL-S2W, when the DL-S2W battery voltage is low thecenter two digits will blink.
If both the DL-D4 and a connected DL-S2W have low batteries, the blinking willalternate between the center digits and all four digits.

When Used as remote Display for DL-S2W, the Receiver plugs in here.
Since the Receiver power is linked to the display unit power,
always keep the Receiver power switch ON.
When used with other LEVELNIC with RS-232C port, connect the PC connection
cable here (Cable model: DL-P5AD or DL-P6.)⑦

⑥ AC Adapter JackPower Jack for external power; connect to the provided AC Adapter.
※ Jack contains diode to prevent current backflow from battery to adapter.
If Adapter is plugged in the Battery will not be discharged, but if AC adapter isnot powered (due to power failure or being unplugged) please disconnect theAdapter from the Display to prevent the battery from draining.
⑦ Battery Case

To open, push up on bottom groove to lift, and pull out.
【Battery Case Open】■ OPERATION【When used as DL-S2W remote display】
1) Install the Receiver included with the DLS2W onto the Input Connector of the Display.
Switch the Receiver power switch to the ON position.
The Receiver is powered through the input connector, so the USB power cable is not needed.
2) Turn on the Display, then turn on the DL-S2W.
Power can be switched on in either order, but turning on the receiving side (the Display) first, andthen the transmitting side (DL-S2W) will reduce power consumption by the DL-S2W.

【With Receiver Attached】【When used as display for other LEVELNIC with RS-232C output】
1) connect the display input connector to the LEVELNIC DATA Out jack using a pc connection cable(sold separately, cable model: DL-P5AD or DL-P6).
(For DL-P5AD, move slide switch to "Computer" setting.)
2) Set the LEVELNIC Function Select Switch (1/2, OUT) to "1/2" so that the output data signal is sent
continuously.
3) Turn on LEVELNIC power, and display power. (They can be turned on in any order.)Display power may be kept off and only turned on when needed.
